My niece and her husband have started regenerative farming this year. They raise meat chickens and hogs, for starters. Beef will happen when they have more fencing.
The chickens live in a ‘tractor’ and are moved around pasture, eating seeds, bugs, plants and fertilizing the ground as they go. The hogs are also pastured - electric fencing is used to move them to different areas ... they aerate the soil, eat the forage and fertilize as they go.
The land was originally monocropped. Manure is being added, plus rotating the chickens/hogs. Beef will be rotated as well. My niece was absolutely thrilled to find a “dung beetle” a few months ago. Mice/voles are returning to land that was barren of life from being sprayed (to kill everything), then used for soybeans, etc.
Regenerative farming is the answer to “climate change” and returning land to the Eden it could be. No artificial fertilizers needed.
Good movie: Sacred Cow (book too, I think).
Regenerative farms: Smith Meadows & White Oak Pastures
My niece is 3 hours away, but there is a farm about 30 minutes from me that pastures/tractors meat chickens, laying hens & beef. With all the crap going on with diesel fuel, food supplies being deliberately reduced, Bill Gates buying up farm land & NOT farming it, restrictions on commerial fertilizers .... grocery shelves are eventually going to be empty if the trend continues. Finding local sources of food, especially direct from farmers/growers is going to be vital for survival.
May be of interest to you and your niece
